Got the build all together and got it to the range to try it out. I had a few different types or ammo with me. The only major issue I had was with the charging handle. It was un-latching and cycling rearward with each round fired. I could grab the charging handle and without depressing the lever pull it past where the latch grabs the upper. Swapped it out at home with a different charging handle that seems to have a much more secure latch. Unfortunately I don't know when I will get back to the range to test it out again but it seems fixed now.
For ammo, I had a couple double feeds, FTE's, and one out of battery detonation, but nothing excessive and seems normal for .22 AR's. Federal 40gr Hi-Shok cycled really good and so did Federal Auto-Match. I tried CCI Quiet and it would not cycle or eject those, in it's defense, the box does say it could have issues in semis. It also did not like Federal Gold Medal Match. I think I put about 200 rounds through it.
The only other thing I want to get right now is the Taccom pressure plug and maybe the reliability kit. Eventually I'll swap out the FSB and MOE hand guard for a longer free float rail and get a Primary Arms red dot or prism scope.
